The hour-long show, which has been done in cities across Europe and this country, takes place at 8 p.m. at Cranston’s Artists’ Exchange.

“It’s the easiest thing I’ve ever produced,” said Kevin Broccoli, whose Epic Theater is staging the unusual evening of theater. Once a theater requests approval to put on the play, he said, the script is sent with the agreement that it won’t be shown to the actor until the curtain goes up. There are no rehearsals, no chances to prepare.

Even Broccoli doesn’t know what the play is about, though there is nothing that says he can’t read it as long as he doesn’t discuss it with Fayan.

“I want to be surprised like everyone else,” he said, “and that’s hard. I was the kid who always snuck into the closet at Christmas to shake the presents.”

While there is mention of the show on the Internet, details are for the most part sketchy. Broccoli said it’s as though the public is honoring the call for secrecy.

What Broccoli does know is that Fayan will be asked to imitate animals, and that there is some audience participation. A friend who attended a recent Boston performance told Broccoli that he was kissed by the actor, although “there was no tongue,” he said.

But he doesn’t know whether that happens at every performance, because there are places in the script where the actor gets to “wing it.”

“I like it when people have expectations and something else happens,” said Broccoli. “A friend of mine thought it might have an improv vibe, but it didn’t.”

Broccoli was also sent a list of props, which includes a chair, stool and a bottle of water.

For theaters that do more than one performance, a fresh actor has to be used each night; otherwise, the contents of the script would be known. That also means that local actors who might want to appear in the show, should Epic do additional performances at some point, can’t attend Saturday’s performance, Broccoli pointed out.

Broccoli said he’s been trying for some time to work with Fayan, who over the years has taken part in numerous shows at Warren’s 2nd Story Theatre. But her busy teaching schedule has kept her from appearing in Epic productions.

That’s not a problem, though, with “White Rabbit,” because it’s a one-night-only event requiring no preparation. All she has to do is show up moments before the start of the show, tear open a sealed envelope containing the script, and “just dive in,” said Broccoli.

Broccoli concedes the gimmick of having an actor go on stage cold may be attracting audiences. But he doesn’t believe the play would have gained the kind of traction it has if it weren’t also entertaining.
